What's this test for?

This test is ideal if you're experiencing symptoms like flank or back pain, blood in your urine, or discomfort when urinating, which can sometimes point to kidney stones or other urinary issues. It's also useful if you've had kidney stones before and want to keep an eye on whether crystal-forming substances are building up again in your urine. Catching abnormal crystals early can help you make changes before a small problem turns into a painful one.

What happens after I get my results?

Your results will show up in your account with each value explained, including what counts as a normal range and what doesn't. If crystals are found, simple next steps might include drinking more water, adjusting your diet, or retesting in a few weeks to see if the levels have changed. If a result comes back that looks serious, such as a sign of a possible kidney stone forming, it's a good idea to seek medical care right away. You can download the full lab report from your account anytime, and the trends feature lets you track your results over time.

Who should consider this test?

People with a history of kidney stones, unexplained back or side pain, or blood in their urine may want to consider this test. It's also useful for anyone with a diet high in animal protein, salt, or sugar, since these can increase the chance of crystal formation. If a family member has had recurring kidney stones, checking your own urine can help you catch issues early.

What symptoms indicate I may need this test?
Watch for sharp pain in your lower back or side, cloudy or discolored urine, a burning feeling when you pee, or urine that smells unusually strong. Nausea or a frequent urge to urinate without much output can also be signs worth checking. If any of these symptoms are severe or come with fever, seek medical care right away.
How can I naturally support healthy urine chemistry?
Drinking plenty of water throughout the day is one of the easiest ways to dilute your urine and reduce crystal buildup. Cutting back on salty, sugary, and high-protein foods can also lower your risk, since these are common triggers for crystal formation. Adding citrus fruits like lemons or oranges to your diet may help too, since citrate can naturally reduce certain types of crystals.
When will I get my results?
Results are typically ready within about 7 days of your sample being processed at the lab. You'll get a notification and can log into your account to view the full breakdown as soon as it's available. No need to call or wait on hold — everything is accessible online.
What does it mean if crystals show up in my urine?
Finding crystals in your urine doesn't always mean something is wrong — small amounts can be a normal part of how your body processes waste. Larger amounts or certain types of crystals, though, can be an early sign that stones may be forming in your kidneys or urinary tract. Simple changes like drinking more water and watching your diet often help reduce crystal levels over time.
What causes abnormal crystal levels in urine?
Not drinking enough water is one of the most common reasons crystals build up, since concentrated urine makes it easier for minerals to clump together. Diets high in salt, sugar, or animal protein, along with certain supplements, can also raise your risk. In some cases, underlying metabolic issues affect how your body handles minerals like calcium or uric acid.
How often should I retest?
If your first result shows abnormal crystals, retesting in 4 to 6 weeks after making dietary changes is a reasonable starting point. If you have a history of kidney stones, checking every few months can help you stay ahead of new stone formation. Otherwise, an annual check is usually enough for general peace of mind.
What should I do if my results are abnormal?
Start with simple steps like increasing your water intake and cutting back on salty or sugary foods, then retest in a few weeks to see if things improve. Keeping a food and fluid log can help you spot patterns that might be contributing to the issue. If you notice severe pain, fever, or blood in your urine, seek medical care as soon as possible.

What this means

Occasional crystals can be a normal finding, especially if your urine sample was concentrated or sat out before testing. Frequent or numerous crystals, however, may point to a higher risk of kidney stone formation. Simple lifestyle changes can often help bring levels back down over time.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
